Application filed June 6,
Another object of the invention is to provide a machine having blades or shovels, which will enter the ground at spaced intervals and be moved across the space between the last and the previous point of entry, so as to thoroughly break up and pulverize the ground the entire depth of enetration. This results in a better seed P bed and the pulverized condition of the soil j acts to retain moisture for an'appreciable length of time.
Another object of the invention is to provide a machine of this character, which may be either a part of or attached to a suitable tractor, by means ofwhich it operated.
A further object 18 the provision of a machine which is simple and durable in con struction, easy of operation and which may be manufactured at a moderate cost.
Other objects and advantages of the invention will appear as the following" description is read in connection with the ac? companying drawings.
In the drawings: 1
Figure 1 is a side elevation'of the invention shown in position upon the rear end of a tractor.
F ig. 2 is a top plan view of the same.
Fig. 3 tional view of the invention per 86. i
Fig. 4 is a detail perspective view of the blades or shovels. i i
Referring to the drawings in detail, wherein like characters of reference denote corresponding parts, the invention is'illustrated as secured tothe rear end of a tractor T. This tractor may be of any suitable construction and the invention may be bolted to the rear end of a tractor frame, as indicated at 10. If desired, the invention may be included as a part of the structure of the tractor.
Specification of Letters Patent.
is an enlarged longitudinal sec- 1919. Serial No. 302,300. I
In carrying out the invention, there is provided a frame which includes spaced parallelslde bars 11, which are connected ad;
jacent one end by means of a bar12, the opposite ends of the side bars 11 being connected to the frame of the tractor, as previously stated.
Patented Feb. 8, 1921. i i
Mounted in suitable bearings inthe side bars 11, is a crank shaft 13, which has secured thereon a sprocket wheel 14:. 'This sprocket wheel is connected to a sprocket. wheel 15 of relatively greater diameter, which is mounted. upon a drive shaft 16 of the tractor frame. 1 i
Depending from the rear end of each of the side bars 11, is a bracket 17 the lower end of which is provided with a segmental gulde slot 18. Operating within the slot 18 1s a shaft 19, the latter having secured thereon a frame which carries the blades shovels to be later described. 1 This frame includes spaced parallel side bars 20, having one of their ends clamped upon the shaft 19. The opposite ends of the bars 2080 are connected by a bar 21. This last mentioned bar is provided with spaced openings 22, for the reception of shanks 23of blades or shovels 24 and 25. The blades or shovels 24: are of substantially fiat formation and are provided with the usual penetrating edge at their lower ends, while the blades or shovels are of knifelike formation and are provided (with a penetrating point .26 and a cutting; edge 27. By this means the blades or knives may be easily forced into the earth to the desired depth. the'cut-. ting edges 27 of the blades orshovels25 actingto breaker pulverize the soil to permit of this operation. The bar 21 is formed with spaced openings 28 to provide means for connection with the side bars 20. These last mentioned bars are also connected shovels 2 1 and 25 at the desired angle at the end of the frame. 1 i 1 Each of the side bars 20 has pivotally connected thereto one end of a connecting rod link 34, the opposite end of this rod through the medium of a shaft or rod 29,
being connected to one of the cranks 35 of the crank shaft 13. 7
From the foregoing described construction, it will be apparent that a rotation of thecrank shaft 13. will'cause the blades or shovels 2e and 25 to be raised and lowered through the action of the connecting link 34, the frame carrying these blades or shovels being moved upon the pivot formed by the shaft 19. A downward movement of the cranks 34 will raise the blades or shovels to be forced into the earth upon a substantially vertlcal line after the manner of operation of hand spading.
It is also the purpose of the invention to movethe blades or shovels rearwardly as the machine moves forwarc, the rearward move- "ment being for a relatively short distance when the blades or shovels will be lifted and again moved forward and forced'into the earth. To accomplish this, there is mounted at. each end of the crank shaft 18, a mu- 'tilated gear 36, the teeth of which are adapted at spaced intervals to engage teeth 37 formed on rack bars 38, which are mounted for pivotal'and sliding movement longitudinally ofthe side bars 11. To this end, the- A rotation of'zthe gears 36 will impart a longitudinal movement to the rack bars 38,
sothat they will be moved from the position shown in full lines in Fig; 3 to that shown by'dott'ed lines inthe same'figure, carrying .the blades or shovels 2a and 25 from the full. This is acline to the dotted line position. complished through the rocker'arms s3 and their connectionwith the shaft 19. hen the blades or shovels 24- and 25 reach the 'limitof their rearward movement, they are raisedthrough the medium of the-crank shaft previously described and are moved forward by means of an arm 45,. which is carried by the connecting bar 12 and actsv underthe' influence of spring as. When the llmit of forward movement has been 7 reachedthe shovels will be again forced into the earth through the action of the crank shaft- 13. This forward and rearward movement of the blades or shovels is made possible by the 'atio of gearing connecting the drive shaft 16' to the crank shaft 13.
